The M330 is a blackbody calibration source utilizing a digital indicating temperature controller that may be set to any temperature between 300 °C (572 °F) and 1700 °C (3092 °F). A precision thermocouple controls the blackbody cavity providing high accuracy and repeatability. A closed-end tube with a 25 mm (1”) aperture diameter is heated by specially manufactured elements.  The temperature controller uses the industry standard PID algorithms to control the emitter temperature to within +/-0.5 °C. The blackbody uses a resistive heater that provide long life. (Running at temperatures greater than 1600 °C for long periods will shorten heater life.)  An independent over-temperature power cutout system is an added safety feature. An internal fan keeps the cabinet surfaces at a safe, comfortable temperature.
